Hydrogen Generation

Hydrogen Generation

Knitted mesh is used in green hydrogen generation electrolysers as an electrical current carrier, conductive spacer or electrode due to its compressible, porous, conductive and resilient properties, ideal for the harsh environment of the electrolysis process.

When produced from nickel, knitted mesh is often used as part of the cathode system in hydrogen electrolysers. Knitted mesh is also available in other materials such as titanium for use in cathode or anode systems.

Hydrogen generation offers a clean fuel from a resource abundant in nature. Green hydrogen is produced by splitting water into hydrogen and oxygen (through electrolysis) using electricity from renewable sources such as wind, solar or hydro energy.

Knitted Mesh is already used in electrolysis as the process conditions can be harsh and mesh offers a reliable solution for equipment to withstand the operating pressure and the caustic nature of the electrolyte solutions (normally potassium hydroxide – KOH).

When energy is released using Fuel Cells there are a number of possible applications for Knitted Mesh in electrochemistry, electrodes, membrane spacers and electrical current carriers.

Knitted Wire Mesh can be produced from any metal including pure nickel or titanium. This strong and flexible material, created from a web of interlocking wire loops (typically 0.15mm diameter) can be used in a wide range of hydrogen generation applications.

Electrolysis Mesh

Due to its highly compressible, conductive and resilient elastic properties, our Knitted Mesh is often used as an electrical current carrier, conductive spacer or electrode, in the extremely harsh environments associated with electrolysis processes.

Our Electrolysis Mesh is often used in Polymer Electrolyte Membranes (PEM) or Ion Exchange Membranes (IEM) and alkaline (non-membrane) zero-gap electrolyser cell applications.

  • Available in Nickel or Titanium
  • Available in infinite range of widths
  • Supplied in 0.15mm diameter wire

Knitted Mesh in Hydrogen Generation

  • Even compressibility (spring force) over the entire surface to ensure an even force is applied to the electrode / membrane
  • Large compression ratios (over 50%) with no plastic deformation to allow for different operating conditions
  • Gap can be controlled from less than 1mm up to any required by stacking
  • No wire breakages, so no risk of puncture to any membrane used (PEM)
  • Open structure allows the gas produced (eg hydrogen) to bubble up to the top for collection
  • Cut-ends (along only 2 sides) can be enclosed to protect the membrane
  • Knitted mesh can be used as the current carrier, spacer or electrode
  • Can be produced from any metal including pure nickel or titanium (typical 0.15mm diameter)
